Surly Steamroller or IRO Angus Complete bikes

Help me decide. I am planning on getting it as a complete bikes. It's very hard because I can't find
a store that has my size, thus can't go for a test ride.

Which wheels are better?

Which component package is better?

Which frame? I guess this is more important. I like the Angus's Reynolds 621 but it has a threaded fork.
Don't know what the Steamroller tubing is? Is it a lot heavier? Don't need a super strong frame I only
weight about 130lbs.

Thanks

Angus is Reynolds 631

ask yourself which has the better warranty on frame and parts... then ask which costs less.

As I understand it, Reynolds 631 is just CroMo 4130 (like the Surly) with a different name, but I could be wrong.

steamroller all the way,... i don't own one but i work in a shop that sells them and have ridden them at work. The frame is surprisingly light and the crankset/surly hubs make it worth the price,... i've heard nothing but good things from people who own them and i would love to have one myself,... also the logos are put on after the clear coating so it's really easy to make it an anonymous bike.

Would have to agree...the Surly is pretty much a clean slate to create with, bigger tires, moustache bars = path racer, drops and no brakes = track bike, calipers and sleek saddle = fixed road. So many options. Iro's can't take the tire range. Nothing wrong with them at all but I'd like the option of 32c tires for crappy conditions.

Thanks, looks like the steamroller is winning. Any IRO fans out there have any thing to say about the
Angus.

I love mine, but it's far from stock. The sizing ****s with some people, it's nearly perfect for me (could stand a shorter TT).

531 is basically the same as 4130. 631 is an improved version of 531, so it's probably not much better than 4130. At least not enough to base a purchase decision on.

Most certainly not! Reynolds 631 is a manganese-molybdenum while 4130 is obviously a chromium-molybdenum.

Reynolds 631 is air hardened and gets stronger after cooling.

But no braze-ons means you're stuck with zip-ties or some other homebrewed ghetto solution if you run a rear brake, right? Sometimes I feel like the only fixie guy out there with two brakes- I would love to upgrade to an IRO, Surly, or Soma steel frame, but I like my rear brake.

Reynolds 531 is not 4130, and Reynolds 631 is DEFINITELY not 4130. Reynolds brand names (531, 631, 853, 753, etc.) all refer to both a specific model of tubings, and the specific materials used to make them. Some are available in a variety of thicknesses and butting, and some are not. They are brand names.

4130 is a material. It is a specific composition of steel. It is made into tubing by a number of manufacturers in just about any thickness, butting, etc. that you can think of.

As I understand it, Reynolds 520 is generally referred to as standard double-butted 4130 steel.

The 525 is a range of cold drawn chrome-molybdenum tubes, all precision butted, using either seamless or welded raw material. The material is suitable for TIG welding and brazing, with lug or lugless construction. 525 will be found in frames with combinations of all 8 tubes, 3 main tubes down and seat tube and seat tube only. The decal will clarify the tubes used by each builder. We recommend 631 or 525 forks for use with 525 road and touring frames.

Reynolds also use the 520 decal for Reynolds chrome-moly tubing made under license to our specification.
So it looks like 520 or 525 is the closest to 4130.

You're right, I was confusing Reynolds 520 with 631.

For however little this is worth, I've noticed that the Bikes Direct Kilo TT has a "Reynolds 520" sticker on the seatpost, and is listed at 4130 on the website, which implies to me that they're one-in-the-same.

Bought a Steamroller !

Thanks guys! I just bought a Surly Steamroller. It came down to availability and price.
There were no Angus in my size at IRO's website and the local dealer I found wanted
$820 for one with upgraded tires and brakes.

What I liked about the Steamroller :
1. threadless fork but with old school lugs
2. wider tire potential
3. sugino rd crank

Overall the Angus's 631 frame ( it is listed 0.45lbs lighter ) was tempting but I think I would
have be happy either way.

Hopefully I will be riding my new Steamroller this weekend
